Pause the video before proceeding. This is a video of the exact same simulation as before {same mass, same spring), only in slow motion with a timer on the screen. There are a few things to note: rst, the equilibrium position of the system is the black horixontal line at the 50 cm mark. The system is in equilibrium when the 100 g label crosses this line. It is the position of the 200 g label that you will use to make your measurements. To make your measurements, pause and un-pause the video, about every 0.15 seconds for the timer in the videos In the Excel Template provided, record at least 60 data points of position and time, The position should be measured by noting where the 200 g label is relative to the ruler. Adjust the parameters in the Excel template until the model seems to fit the data, Take the angular frequency and phase out to a precision of no more than two decimals Record the parameters below: Best A: Best to: Best 1:: Best ya: From the best fit a), compare with the to found in part 1 with a percent difference. Discussion Questions 1) Repeat part 1 two more times. What is your average period? Is it signicantly different than your first measurement? 2) From part 1. calculate the spring constant How would your answer to the previous question change if the spring constant were increased? 3) What value of angular frequency best fits the data? What is the % difference between the two values? 4) What phase best fit the data? Can you explain why it might not be zero? 5) How would you need to adjust the angular frequency for your model if the same spring were used with a smaller mass, holding the amplitude and offset constant? _ v + 100% 871 words U?
